My testing seems to show the IP address rather than domain name is passed to
the client for region/UDP.
I have one region using ExternalHostName=SYSTEMIP and the others using
ExternalHostName=something.dyndns-mail.com
I run Opensim 0.7.0.2 on a VISTA system, stand alone mode, client access
both local and external, NAT loopback on.
All that works fine.
To test I added a HOSTS file entry on the server PC using 127.0.0.1 for
something.dyndns-mail.com.
With that change I was able to login a client on the server PC without
issues.
Logging in from a local non-server PC I cannot start at or TP to a region
that has ExternalHostName=something.dyndns-mail.com. Login fails at the
handshake step. However, I can login on that PC starting at the region with
ExternalHostName=SYSTEMIP. Handshake works.
I interpret all that to mean the server is sending the IP address to the
client for the UPD communication. If the server was passing the domain name
I would expect no Client issues on my non-server PC. I'm only changing the
IP address of my ...dyndns... domain name on the server PC for this test.
In fact, I can remove the HOSTS entry while the server continues to run.
After that I can again login on a local/non-server PC with no problems.
One other item I found that suggests IP addresses are being passes rather
than domain names is the Entity Transfer Module entries in the server log
2011-04-04 22:24:53,759 INFO -
OpenSim.Region.CoreModules.Framework.EntityTransfer.EntityTransferModule
[ENTITY TRANSFER MODULE]: Starting to inform client about neighbour 999,
999(174.124.181.36:9009)
Network isn't my specialty so I may have misinterpreted things. I welcome
other explanations.
(Multimedia seems to be handled by passing the domain name - but that's
another story.)
